GULE of AUGUST, the day of St. Peter ad vincula, which is celebrated on the first of August. It is called the gule of August, from the Latin gula, "a throat," for this reason, that one Quirinus, a tribune, having a daughter that had a disease in her throat, went to Pope Alexander, the sixth from St. Peter, and desired of him to see the chains that St. Peter was chained with under Nero; which request being granted, and she, kissing the chains, was cured of her disease; whereupon the Pope instituted this feast in honour of St. Peter; and, as before, this day was termed only the kalends of August, it was on this occasion called indifferently either the day of St. Peter ad vincula, from what wrought the miracle; or the gule of August, from that part of the virgin whereon it was wrought.
